Energy Savers: Overview
Heating and cooling your home uses more energy
and drains more energy dollars than any other system in your
Typically, 44% of your utility bill goes for heating and cooling.
What's more, heating and cooling systems in the United States
together emit over a half billion tons of carbon dioxide into
the atmosphere each year, adding to global warming. They also
generate about 24% of the nation's sulfur dioxide and 12%
of the nitrogen oxides, the chief ingredients in acid rain.
No matter what kind of heating, ventilation,
and air-conditioning system you have in your house, you can
save money and increase comfort by properly maintaining and
upgrading your equipment. But remember, an energy-efficient
furnace alone will not have as great an impact on your energy
bills as using the whole-house approach. By combining proper
equipment maintenance and upgrades with appropriate insulation,
weatherization, and thermostat settings, you can cut your
energy bills and your pollution output in half.
